TRAIN YOUR EYES FOR PUTTING
I cannot stress enough upon the players that I instruct the role of their eyes when putting. The eyes are involved in almost every facet of putting except for the actual stroking of the ball, and even then they can have a detrimental effect.
When you arrive at the green the eyes need to take in the lie of the land. The more detail the eyes pick up the easier it is to pick a line and feel and trust the distance.
In set-up, a drill I use on tour is practising with stringline above the ball, between ball and hole, to not only improve the line of the stroke but also to train the eyes to be square to the path and visualise the line to the hole. Another training aid that improves the role of the eyes is a putting mirror
Once the eyes have played their active role in reading a green and lining up a putt, they need to take a passive role. Many strokes are ruined by active or busy eyes following the putter head or the ball on its way to the hole. Listen for the ball to drop is a good tip to quieten the eyes and keep the head still. 3 OTHER DRILLS TO IMPROVE EYE AWARENESS. 1) Practice with your ball on a coin and make sure you see the coin after the ball is struck. 2) Once lined up, turn your head to look at the hole and hit the putt watching the target, Jordan Spieth. 3) Line up the putt and stroke the ball with your eyes closed. Try to judge the result by what you felt, rather than saw. Former student David Howell leaves a gap between ball and putter in his set up and strokes his putts focusing his eyes on the grass between them.
